The document outlines a program for interfacing an ESP8266 Wi-Fi module with an Arduino to control a built-in LED. The provided code turns the LED on for one second and off for two seconds in a continuous loop. The result is a blinking LED pattern demonstrating the active low functionality of the ESP-01 module.

Program 8 : Interfacing ESP8266 Wi-Fi Module with Arduino

Program Code :-

void setup() {
pinMode(2, OUTPUT); // Initialize the LED BUILTIN pin as an
output
}

// the loop function runs over and over again forever


void loop() {
digitalWrite(2, LOW); // Turn the LED on (Note that LOW is the
voltage level
// but actually the LED is on; this is
because
// it is active low on the ESP-01 )
delay(1000); // Wait for a second
digitalWrite(2, HIGH); // Turn the LED off by making the voltage
HIGH
delay(2000); // Wait for two seconds (to demonstrate
the active low LED )
}

Result :-
When this code is uploaded to an ESP8266, the built-in LED will blink in the following pattern:
1. The LED will turn on for 1 second.
2. The LED will turn off for 2 seconds.
3. This on/off cycle will repeat continuously.
